Advanced Automatic Microfiche Scanner


 

The Technology
Fully Automatic Digitization

Many microfilm archives encompass very large quantities of individual microfiches. With the fully automatic digitization technology of the DRS DIGITIZER, they can be recorded problem-free and saved as a file. Every file can be edited, digitally archived, and analyzed with an image processing program.

CCD Full Frame Chip Technology

Unlike other conventional systems, the DRS DIGITIZER uses a high-resolution CCD full frame chip camera in order to create an image with up to 256 grayscales. Optimal illumination occurs via a non-wearing LED lighting technology specially designed for DRS. Every document on a microfilm is automatically recorded and digitized with high quality. Even sophisticated originals are perfectly readable.


 
 

Gentle Feed System

The antistatic repository contains several hundred microfiches in all prevalent sizes. By means of a pneumatic feed system developed by us, the originals are transported to the light table with the utmost care. Even electrostatically charged fiche and jackets are reliably separated by an air current.

Powerful Software

The image recognition and processing software of the DRS DIGITIZER determine the precise position of every individual document on the microfiche. Every document is individually surveyed, aligned and cropped. The image file can be stored for processing in different file formats according to the customer's desire.
